Palacio de Correos, Renaissance Revival postal palace in Plaza de la Rinconada, Valladolid, Spain.

Palacio de Correos is a postal building in Renaissance Revival style located at Plaza de la Rinconada. The structure features grand arches across two main floors and traditional red brick masonry, with a third level showcasing rounded windows.

The building arose from a 1913 competition won by architects Jerónimo Arroyo and Luis Ferrero Tomás, with the definitive project signed in 1922. It was commissioned to house new communication technologies such as the telegraph on a central triangular plot. In the 1970s, the original balustrade and corner tower were demolished and a fourth floor added.

The facades combine brick and stone, a pairing praised by the local press when the building opened. Craft trades shaped the decoration: Renaissance-inspired iron grilles, tiles with 16th-century motifs, and stucco mouldings taken from Plateresque and Renaissance models. The style was chosen as a Spanish national architecture, drawing on Plateresque, Renaissance and Baroque sources.

The building stands on a triangular plot at Plaza de la Rinconada, between Plaza Mayor and the church of San Benito, so its corner entrance is easy to miss. Inside, the layout is organised around a covered central courtyard that serves as the operations hub. The main post office functions remain in the building.

In the 1970s, the original balustrade and tower were removed and a fourth floor was added. These alterations significantly changed its classical appearance.
